The noun quim was a Victorian-era word that was used specifically to refer to the fluids produced by the vagina, specifically during orgasm. In modern usage it is primarily heard in British slang and is a derogatory or vulgar term for the vagina itself. The word is rarely used today in English slang but used in Wales as an insult rather than the above meaning. The word may be related to Welsh 'cwm' meaning 'hollow' or 'valley'.
